Evaluation of the flexural properties and failure evolution of a hybrid composite manufactured by automated dry fibre placement followed by liquid resin infusion

The market for composites is developing rapidly due to the widespread general requirement lightweight design in various industries. However, proliferation of fibre-reinforced limited partly lack ductility associated with these materials. Hybridisation fibres has emerged as an important strategy increase polymer composite In present work, water based dispersion was used develop a dry fibre carbon tape and hybrid glass/carbon which are both compatible automated deposition techniques. Dry preforms were manufactured using laser-assisted placement (DFP) laminates subsequently vacuum assisted liquid resin infusion. exhibited higher flexural strength (8%) strain-to-failure (58%) relative laminate. To understand failure modes, X-ray micro-computed tomography conjunction interrupted tests monitor evolution damage. progressive analysis revealed that composites, damage propagation delayed staggered arrangement glass fibres. majority located tows.
